Condensation on our windows looks harmless but if it is allowed to build up and mould begins to form it can be problematic to both your home and your health. Condensation occurs when humid air encounters cold surfaces such as wall and windows. Remember that science lesson now? When the vapour in the air becomes cold it transforms back into a liquid, hence why condensation shows itself in the form of tiny droplets of water, often most noticeable on our windows in the morning when the air outside is at its coolest.
Now we understand the cause of condensation, it is clear that the best solutions for condensation are heating (to keep susceptible surfaces above dew point temperature) and ventilation (to expel the warm, moisture-laden air to the outside).
The cures for condensation are heating (to keep surfaces above dew point temperature) and ventilation (to drive out the warm, moisture-ridden air to the outside).
